POLISHING-MACHINE Specification of Letters Patent.

Patented Feb. 4', 1908.

Application filed October 1,1907. Serial No. 396.302;

.useful Polishing-Machine; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame This invention pertains to a new and useful surfacing machine; andthe invention, in its broadest aspect, resides particularly in the newand especially constructed means for raising and lowering the abrasiveor buding disks, or in other words the polishing mechanism, incombination with the general construction of the apparatus.

The invention cites .as a further object to provide a simple, efficientform of frame for supporting the motive power, the polishing mechanismand the means for raising and lowering the said, polishing mechanism;

A further object of the invention dwells in the special construction ofthe frame, which consists of one solid casting horizontally disposed,"as clearly illustrated; a still further object of thejinvention residesin the disposition of the frame, relative to the motive power, and thepolishing mechanism, the means for transmitting motion to the saidolishin mechanism and to the raisin and lowering mechanism.

This invention comprises l 'urther objects and combinations of elementswhich will be hereinafter more fully described, shown in theaccompanying drawings, and the novel features thereof will be pointedout by the appended claims.

The features and elements and the arrangement thereof for accomplishingthe objects of the invention may be changed and varied, that is to say,in a practical application of the apparatus, with an understanding thatthe changes and variations accruing from said application are limited tothe scope ofthe appended claims.

. To obtain a full and correct understanding of features, elements andadvantages, reference is to be had to the hereinafter set forth inconnection therewith, wherein Fi ure 1 is a side elevation of thesurfac- D u I a mg machine, showing the raising and lowering mechanism,for the polishing mechanism in side elevation. Fig. 2 is a sectionalview on line 22 of Fig. 1.

spective view of the raising and lowering mechanisms for the polishingmechanism. Fig. 4 is a sectional view through the buffer wheel, showingthe space in which oil is 0on 'tained, preferably linseed oil. Fig. 5 isa side elevation illustrating a modification, in which the motive poweris vertically disposed, and the frame is of a triangular form. Fig. 6 isa sectional view on line 6 6 of Fig. 5. Fig. 7 is a detail erspectiveview of the means for raising and lowering the polishing mechanism.

In regard to the accompanying drawings, wherein similar referencecharacters indicate corresponding parts in the several illustrations, byfigures, 1 designates the frame of the apparatus which is horizontallydisposed, and is angular in contour, and is provided with bearings 2 atthe front and rear thereof in which shafts 3 and 4 are journaled, asclearly shown. The shaft 3 has provided upon its lower end an abrasiveor buffing disk 5, upon the lower face of which felt or sandpaper isfixed by means of a clamping ring 7, which has threadedconnections withthe said disk; this disk is provided with an inner chamber in. whichoil, preferably linseed oil, is contained, as clearly shown. The lowerace of the said disk is perforated, so as to allow the oil to percolatetherethrough, so

understood from the drawings. The shaft 3 is also provided with a pulley8, around which the pulley 10, fixed to the lower end of the shaft 2, asclearly shown. Fixed to the upper end-of the shaft 2 is a beveled gear11, which is in mesh with the beveled gear 12 mounted upon the drivingshaft 13 of the motor 14, which is fixed to the upper face of the saidframe, and is supplied with current in any suitable manner. V

The frame 1 is provided with a pair of caster wheels 15, which are fixednear the rear end thereof. as clearly shown. The front 7 portion of..16'fi8.111i5 provided with a bear- {ing 16, in which the shaft 17 of asingle caster wheel 18 is journaled, as clearly shown in Fig.

l from the said frame is a pair of members 19 i between the upper endsof which a suitable l handle 20 is fixed, for the purpose of steering asto cooperate with the felt as' will be clearly the belt 9 travels, whichbelt also travels over Fig. 3 is a detail per- 1. Projecting rearwardlyand upwardly polishing mechanism.

the apparatus over the surface to be polished,

with a pair of bearings 23 in which the lever.

24 is pivotally mounted, as clearlyshown.

This lever is forked at .15 lower end, as showrr' at 25, and the arms 26thereof are slotted, as at 27, to receive the pins 28,projectinglaterally fl'ulll the sleeve 29, carried by the upper end ofthe said shaft 3. This sleeve is prevented from downward movement uponthe shaft 3 by means of a shoulder 30, and is pre vented from upwardmovement by means of the washer 31 and the nut 32, as will be clearlydepicted from Fig. 1 of the drawings.

The upper and rearward end of the lever 24 is provided with a portion 33which is angularly disposed to the body portion of the said lever, andis for the purpose of being engaged by the Ushaped portion 3% of thesliding meml r 3'' for the purpose of raising and lowering the saidshaft 3, which would, as

will be clearly manifest, carry therewith the This slide is movable uponthe bar 21 a d is provided with a rearwardly p1'oje.. i11g .nember 36,which is provided with a downwardly disposed handle 37, as clearlyshown; this member 36 having its handle 37 is for the purpose ofoperating the said slide upon the bar, which would cause the said lever24 to oscillate, so as to raise' and lower the polishing mechanism. v

In Fig. 5 the frame is triangular in top view and the motor isvertically disposed so as to provide its driving shaft with the pulley10 with which the belt 9 engages. The means for raising and lowering thepolishing mechanism is identical with that shown in Fig. 1, with theexception that the bar 21 is fixed between the bearing 2 and a clamp 38carried by the said motor, as will be clearly manifest.

From the foregoing, the essential features, elements and the operationof the device, together with the simplicity thereof, will be clearlyapparent.

Having thus fully described the invention,

what 1s claimed as new and useful by the protection of Letters Patent,is

1 In a surfacing machine, a frame, a

motor having a driving shaft mounted there-' on, said frame having atone end a olishing mechanism having a shaft while t e other end isprovidedwith gear mechanism for transmitting power to the polishingmechanism, and a belt forming the medium for transmitting the power fromthe gear mechanism to the polishing mechanism,means for raising andlowering the olishing mechanism comprising. a pivotaly-mounted'leverhaving an angularly disposed rear ortion and pivotally mounted at itsfront en to the shaft of the polishing mechanism, a bar having a movablymounted slide to engage the angularly disposed rear portion so as toraise and lower said polishmg mechanism.

I .2. In a surfac'ing'n'iachine, a frame, a polishing mechanism at oneend thereof having 'a shaft, a motor fixed to the frame, gear and beltmechanisms for transmitting power from theopposite end of the franie tothe olishing mechanism, meansfor raising and J owering said polishingmechanism compris ing a lever having an angularly disposed portion andpivoted tothe shaft of the polishing mechanism, a bar, a slide movablymounted thereon and adapted to engagesaid angulary sposed portion forraising and lowerin tl rearwardfr.

3. In a surfacing machine, a polishing mechanism, a motor having gearand belt mechanisms for operating. the polishing mechanism, meansdisposed and so porte upon the upper portionof the motor or raisingand-lowering the polishing mechanism comprising a lever having angularlydisposed means, an angularlydis osed bar, a member slidable thereonadapts to engage said angularly disposed means for raising and lowering95 the polishing mechanism.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
